[libvirt-users] cgroup error starting domains

Hi, I've got a small problem using libvirt-1.0.5.1 (with the latest patch in the v1.0.5-maint branch on git added). I'm using slackware64-14.0 but the situation is exactly the same described on a debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707201 When trying to start a domain I got error: Failed to start domain debian-wheezy-xfce error: Unable to initialize /machine cgroup: Invalid argument with this in libvirtd.log virCgroupDetect:373 : Failed to detect mounts for /machine qemuInitCgroup:425 : Unable to initialize /machine cgroup: Invalid argument and the error goes away if I unmount /sys/fs/cgroup. Reverting to 1.0.4 fixes this, but this exposes another thing that I report even if I'm not sure it's an error: if I create a domain with 1.0.5.1 (I use the latest virt-manager to do this), in the xml of the domain there's a line that doesn't seem to have the close tag <controller type='pci' index='0' model='pci-root'/> If I revert to 1.0.4 the domain with this line in the xml doesn't even get listed between the available domains and I got this in libvirtd.log virDomainControllerDefParseXML:4838 : internal error Unknown controller type 'pci' deleting the interested line make it available again. Please let me know if you need further informations on the matters. Matteo
